If you're really into the idea of doing a drastic change (meaning three or more shades lighter or darker than your natural color or switching it completely), visit the salon. At-home hair color should be about maintaining the shade that was designed for you by a colorist, not major changes, advises Dorram.
Cunningham first used chance in Sixteen Dances (1951) to determine the order of various segments into an established structure of dark, interlude, light, interlude, etc.; he also used charts and chance for the choreography and spacing of several dancers during one of the interludes.
The other principle that Cunningham and Cage shared was the use of chance procedures in the composition of their works. Cage carried them through to the process of realizing a work in performance, while Cunningham has preferred to use chance not in the performance of his choreography but in its composition.
